Question

According to Le Chatelier principle, an increase in
the temperature of the following reaction will
N, +0,=> 2NO - 43200 cal
(A) Increase the yield of NO
(B) Decrease the yield of NO
(C) Not effect on the yield of NO
(D) Not help the reaction to proceed​

Answer 1

Answer:

I will try to explain in detail.

See that the heat data is given on the product side and a negative sign is given.

So, we can conclude that it is an endothermic reaction.

Now, endothermic reaction always absorb energy/ heat.

So if we apply heat, more heat will be absorbed and more products will be formed. This is on the basis of Le-chateliar principle.

So, the option A) is correct.

Please check the answer in the assignment book.

Hope you will be able to understand.

Answer 2

The reaction is,

N+O----->2NO-43200 cal

OR

N+O+ 43200 cal-----> 2NO

(On moving energy to the left side, it becomes positive)

As it is an endothermic reaction, when we increase the energy(temperature), the energy on the side of reactants increases, so reaction moves more towards products to reduce the effect.

Thus, correct option is A)
